Istio Rate Limiting not working on apps other than bookinfo

Hi I’m applying Rate Limiting on istio 1.1.6 using the official documentation link https://istio.io/v1.1/docs/tasks/policy-enforcement/rate-limiting/.

Rate limiting works on the bookinfo sample application as shown in the documentation link. But when I try it on some other app it doesn’t work. I have tried a lot but no luck.

Can someone please guide me in this regard.

The goal I am trying to achieve is to apply a default rate limit on all the kubernetes services.

Any reason you are using Istio 1.1.6? It’s out of support. afaik…
